Figure 1 Schematic rendering of rotational misorientation in animal and neuron behavior. Rectangular box seen from above. Mouse is shown location of hidden food at C, then disoriented and reintroduced to the box. It digs at C on about half the trials, but on the other half, it digs at R, the rotationally equivalent location. Strongly colored blob is heat map of the firing seen in a typical hippocampal place cell. On half the trials, the cell fires here when the disoriented mouse is returned to the box to search for the food, but on the other half it fires in the rotationally equivalent location, which is indicated by the faded heat map. On those trials, the mouse digs at R rather than at C. Dashed lines indicate the 1st and 2nd principal axes. Black stripes on one end wall are a salient non-geometric orientation cue, but they are ignored.
